" So far, I'm finding it to be an extremely useful device, with a screen that works very well for many types of documents, including scientific papers and technical manuals. The Whispernet data connection is really cool and provides a strong differentiator for this reader versus others on the market right now...

While seeming a little too small at first, I think Amazon got the size just right. The screen is large enough to display detailed content, yet the Kindle is still portable enough to take with you everywhere...

I tried a bunch of complex PDFs on the Kindle, and all of them rendered flawlessly. The images below illustrate various documents, including a research paper, a page from my Ph.D. thesis, a spec sheet from a microelectronic component, and pages from Apple's Human Interface Guidelines. The text and vector art are sharp and clear, but text that was already in small print within two-column research papers might be difficult for people with poorer eyesight to read.

Unfortunately, the only way to zoom in on a PDF is to rotate the device into a landscape mode, which widens the PDF to fit that orientation. It would be very nice if Amazon were to add a portrait zoom function in a future firmware update. "

Brad doesn't seem to write notes on PDFs though, and that's not possible anyway with Amazon's current Adobe licensing. As mentioned before, for adding notes, you'd have to convert a copy of the PDF to MOBI/PRC via one of 3 free utilities, mentioned in earlier articles here, to get a copy which pays less attention to intended layout but allows highlighting and notes added as well as all text to be findable when doing a full search of the Kindle contents.

Also, here's that video of the DX used for pilots' approach plates; it's the most accurate representation I've seen of the DX rendering PDFs.

Some photos I took earlier of the DX screen, in vertical and then landscape modes are here.

Updated for minor corrections and addition of video information for those who missed the approach plates story.

Questions & feedback are welcome in the Comment areas (tho' spam is deleted). Thanks!

Am often away much of the day, and postings won't show up right away. Posts done to use referrer-links may never show up.

Usually, am online enough to release comments within a day though, so the hard-to-read match-text tests for commenting won't be needed this way.

Feedback and questions are welcome. Thanks for participating.

Technical Problems?If you're having problems leaving a Comment, Google's blogger-help asks that you clear the 'blogger.com' cookies on your browser's Tools or Options menu bar and that will fix the Comment-box problems (until they have a permanent fix).

IF that doesn't work either, then UNcheck the "keep me signed in" box -- Google-help says that should allow your comment to post (it's a workaround to a current bug). Apologies for the problems.

TIP: There's a size limit. If longer than 3500 characters or so, in a text editor, make two posts out of it.
